^^ good points by Azzork. Dday, believe me I've been through enough urges to tell W something, still do. These things come out on their own or they don't need to be said. Right now your W is going to say she's happy withour you and there is nothing you can do about that. You try and fight it and all your doing is cementing the idea in her mins that your the problem. A problem that she will continue to look at and want to run to away from to find her happiness. Get out of her way in that regard and let her see where it leads.
Please, please do not ask her to tell you if she ever changes her mind. It makes it look like you can't live without her and will wait around for her forever. The attitude you need to move toward (without needing to tell her but through your actions) is that while you love her you recognize your value as a man and are moving forward with your life and if D is what she wants she can have it. That you will be fine. You said it before so don't feel the need to say it over and over.
Another point, don't think you will be the one to break through her fog. You can do everything perfect and it mean nothing. Your actions may influence it but it breaking will be mostly dependent on her and will happen on her time frame, if at all. Her path, remember that.
Accept what is, let go of what was, and have faith in what will be
